Abstract
Information, such as a calling subscriber number, is furnished to a called subscriber, regardless of the type of subscriber terminal that is accommodated by an access network, which is provided independent of a local exchange, and regardless of whether a connection is a wireless connection or a wire connection. A calling subscriber information notification system includes a local exchange, and an access network, located independent of the local exchange, for accommodating a plurality of subscriber terminals. When a call is made by one of the subscriber terminals, the access network receives, from the local exchange, a signal message including information concerning a calling subscriber terminal, and when a called subscriber has been registered for a called number notification service sends to the called subscriber, the information concerning the calling subscriber terminal that has been received from the local exchange.
